Abstract One of the arguments against an increased use repair is that, due to constantly growing progress, often already outdated component would be restored. However, refurbishment also allows a modified in order upgrade it state art or adapt changed requirements. Many existing approaches regarding Design for Upgradeability are based on modular product architecture. In these approaches, howeve...

The concept of zero waste is an ideal situation that will require different solutions for categories waste. Electronic (E-waste), the fastest growing category solid hazardous presents various unique challenges. product repair, reuse and remanufacture (3re) are crucial effective source reduction E-waste integration electronics industry into a circular or zero-waste economy framework. Increasingl...

Kendaraan bermotor sebagai alat transportasi saat ini menjadi salah satu kebutuhan penting untuk manusia. Jumlah sepeda motor terus meningkat setiap tahunnya. Hal menyebabkan sampah atau limbah berupa komponen yang telah rusak dari sebuah kendaraan juga meningkat. Saat ini, beberapa bentuk tersebut dapat dilakukan recycle agar materialnya dimanfaatkan kembali. Beberapa sebenarnya masih digunaka...

Current existing UK housing stock is responsible for 27% of UK CO2 emission. Refurbishing this housing stock can contribute to the 80% CO2 reduction by 2050 as a UK government target. However, there are barriers to refurbish a house due to high initial cost and lack of knowledge and skills in construction sector. To accomplish the CO2 reduction target, BIM should be utilized because BIM is capa...

Construction customers are persistently seeking to achieve sustainability and maximize value as sustainability has become a major consideration in the construction industry. In particular, it is essential to refurbish a whole house to achieve the sustainability agenda of 80% CO2 reduction by 2050 as the housing sector accounts for 28% of the total UK CO2 emission. However, whole house refurbish...

A reverse logistics system is a network of transportation logistics and processing functions that collect, consolidate, refurbish, and demanufacture end-of-life products. This paper examines centralized and decentralized models of decision-making for material flows and associated transaction prices in reverse logistics networks. We compare the application of a centralized model for planning rev...

The Direct Laser Deposition (DLD) process has shown significant results in manufacturing due to its relevant flexibility refurbish high-performance components (e.g. turbine blades or disks) fabricating complex shaped parts. solidification microstructure during the DLD process, is known be controllable using different parameters that induce changes grain structure, micro-segregation, and phase t...

The environmental performance of existing buildings can have a major role in achieving significant reductions CO2 emissions: In the UK, around 75% 2050's housing stock has already been built. While building improvement efforts mostly focus on operational performance, impact is result processes that occur throughout their life cycle. To achieve emission an economically viable way, this study use...

With the help of circular strategies, products can be used longer (i.e., reuse, repair, and refurbish). Products that are difficult to use will recycled efficiently. The present paper provides actionable guidelines for reducing environmental impact at all stages a product’s life cycle, including manufacture assembly materials make up product, impacts during use, final disposal, as well specific...

To increase the impact that Zero Emission Neighbourhoods (ZEN) can have in effort to decrease CO2 emissions, refurbishment of existing building stock is a parameter should be considered. The literature contains work on optimization models for energy system neighbourhoods taking into account emissions but fails buildings. This paper addresses this option and presents an model designing cost-opti...
